Hi When I get clicks (in google links ads) and $0 that means what? User clicked in the links but did nothing in the next page? Or... means that when I see clicks in adsense reports the user clicked in my ads and then clicked in google ads? thanks
I'm guessing, if you're brand new to AdSense, it means they've clicked a PSA (Public Service Ad) - these ads don't pay. Edited: My bad - I misread the 'link unit' bit. See wissam's answer below.
Google : Your reports will not track clicks on the link unit topics, but will log clicks on the Google ads from the resulting page.
